- To @ZZ/whom t may concern:

Be it known that I, JOHN EDGAR Cox, a citizen of the United States, residingv at East San Pedro, in thegcounty of Los An-y geles and State of California, have invented new and useful Improvementsin Fish#L novel features herein Trimming Machines, of which the followinOf is a specification," s

vily object isfto makea fish trimming m`a chine, and any `invention, consists .of the' shown, described and claimed, s f y Specific-ally my-object is to make a machine which will cut they heads and tails from fish leaving thebodiesof a uniform length.

Figure 1 1s a top plan view ,of a fish trimming machine embodying the principlesof; my invention, the view being'taken looking in the direction indicated by the arrows 1 in Fig. 2 is a .side'elevation looking` in the direction indicated by the arrows 2 in FigsA land 3. n

Fig.'3 is a verticalbross ssectionon the Fig. 4-is ra fragmentary perspective illustra'ting the operation of cutting the head and tail from the body of a fish. Fig. 5 is afragmentary perspective illus-Y the head and wremoving the entrails Jfrom the body with' thehead.

TheV side bars 1 and 2 are rigidly connecte'V4 ed bythe end bars 3 yand 4 tofmakev a rec` tan guiar rigid frame'. The frame is mounted on legs 5 connected to the side bar 2 and legs 6 connected 'to the side bar 3, the legs 6 being longer than the legs 5, so as to mount the frame at an angle of aboutl30o relative" to a horizontal plane. I

A driving shaft 7 is mounted through the sideV bars 2 and 3 near the longitudinal center, and a driving'sprocket 8 is fixed upon one end of the shaft 7. vkAn idlerfshaft 9-is mounted "through theforwar-d ends of the side bansl and 2. Asecond idler shaft 10 is mounted through theside bars 1 and 2A half way between the shaft `7 A'and the shaft 9, and a third idler shaft 11 is mountedy through the rear ends of the side` bars 1 and 2.

The body conveying chain 12 runs over a driving sprocket 13 xed upon the center of the shaft 7 and over idler sprockets fixed upon the shafts 9, 10 and l1. The head con- Y Specification of Letters Patent.

s f In a like manner the tail conveying chain 16 runs over -a driving sprocket 17v fixed upon `the shaft 7 and lover idler sprockets up-onthe shafts Sand 10. The chains 12, 14 |and 16 run in channel 'iron guideways 18, 19 and 20 to hold Ithe chains from sagging andfto `holdtherchains from moving side-H wise. s s

A. bar 2l is mounted along the lower side ot the body conveyer of which the chain 12 is a part and; between the cutters and the discharge end of the conveyer @to prevent the bodiesfrom sliding endwise from 'the conveyer. y,Thefbody conveyer pans 22 are `securedyto -thecQnVeyerchain 12 and are open at bothends and adapted to' receive a single fish body.v

- Thehead conveyer pans 23 yare secured toy except that they are closed at'itheir outer endsto preventtheheads from sliding out of the panslendwise.y The tail conveyer pans 24 are secured tothe chain 16 and are similar 'to thel body conveyer pans.

The bracket 25 has bearings 27 f and 28 in its upper end, and the bracket 26'ha`s bearings 29 and 30 in its upper end. The countershaiit 31is mounted n l in the-bearings 27 ,28, `29 and 30. The levers 32 and 33 are vpivotally mounted upon` the shaft '31', the lever 32 being Vbetween the i ybearings 27 'andi 28,andtheleverVv 33 being between'the bearings"29 Land 30. lPoste 34 and extend upwardly from the side bars l and 2, andkfthumb screws 36 and 37 are inserted through :the levers 32 and l33 and intoy holes 38 in the posts, so that by moving the thumb screws from one hole to another the levers may bertilted as'. desired and held in their adjusted positions. ,f

, A spur gear'39is fixed upon the shaft 31.

chain "41 f connects thef sprocket 40l to a sprockety 42 fixed upon the shaft 7. The cutter shaft 43 is mountedin bearings 44 and 45 in the ends of the levers 32 and 33, and a spur gear 46 is fixed upon the end of the shaft 43 in mesh with the spur gear 39,

. kA sprocket 40`is fixed upon the shaft 31. A n

` The lower head Cutter 47 is fixed upon the shaft 7, and the uppervhead cutter 48 is fixed upon the shaft 43. The lower tail eutter 49 is iixed'upon :the shaft 7, andthe upper tail cutter 50 is fixed upon the shaft 43. The cutters 4f? and 48 operate between the pans 22 "and 23, and the cutters 49 and 50 operate between the pans 22 and 24.

Y, The cutters 47, 48, 49 and 50 are substant'ially'alike and eaeli cutter has points 51 and coneavities `52 between the points, the points 51 *and the concavities 52 forming overlapping cutting edges, So tha-t the points overlap more than the concavities.

Attention is called to the fact that thc had'eoiiveyer 'pans l23 and the tail conveyer pans 24 ti-avel forwardly around yth'eshaft 7 while `:tl-ie bc'lyfe'onveyer pans 22v travel still farther-forwardly'aroimd the shaft 11. The upper cutters 48 and 50 upon the shaft 45 are Set somewhat in `front of the lower cutters 47-and V49 upon the shaft V7, and the upper cutters are raised-or lowered by manipulating the thumb Vscrews 36 and 37 and thelevers 32 and 83.

In the praeti'ealoperation the fish 'are placed Aoneat a ltime in the conveyer pans with the bodi'esof the fishin the pans 22,

'the heads extending into the pans 23, and

tai'lfsfextending into the pans 24. VThe conveyers yop'ei'at'e continuously `atfa com p'aratively l'slow speed, and -as the fish pass 'the cutters i-the cutters are timed relative to the `pans fand relative to eachother, so that-'the'fish will pass into the concavities 52, and when the fc'utters come "toward each other on Yopposite vsides fof the iish the first Y v action of 'the 'cutters'i's to eut the case of Y as claimed.
